Overview

ROHM offers thick film resistors in the low resistance range between 11mΩ and 100mΩ that are robust against ambient temperature fluctuations. The unique structure improves thermal dissipation for superior rated power (1/3W) compared to similarly sized standard short terminal products. < External Dimensions >
